Solid State Drives (SSD) do in fact fail so at some point you may need SSD data recovery.
They do wear out. You can only write a sector so many times and the the sector stops working.
Data on the chips are constantly being shifted. They do this for “wear leveling”. Since any given sector can only be written to so many times before it fails they constantly rotate the data on the chip (like a game of musical chairs). That way if one sector is constantly written to, it would not burn out that one location making the entire device useless.
Data is written in a different manner than a platter based hard drive. On a hard drive they magnetize bits. If the bit is magnetize it is a 1. If it is not magnetize it is a zero. On a SSD a bit is charged like a battery for a 1 and not charged for a zero. A SSD is not good for storing data for long term. If you put a SSD in a drawer for a year or two you may end up with no data. Turning it on once a month will prevent you from losing data.
Unlike a hard disk which contains spinning platters and mechanical read-write heads, the SSD drives have no mechanical parts. They’re built from components such as transistors and flash chips. This is why they are called Solid State.
Solid state data recovery is becoming increasingly more popular. At the moment, there are two types of flash memory chips which are NOR and NAND. Both of the chips contain cells in a grid, but the wiring between the cells is slightly different. NOR flash chips are wired in parallel grid formation. NAND flash chips cells are wired in a series. NOR cells contain far more wires, so they are larger and more complex. NAND chips require fewer wires and can be filled on a chip with a larger density. Thus, NAND flash chips are less expensive and can read and write data quicker. NAND flash chips are at the moment the more ideal storage technology and are currently the more popular flash memory technology solid state drives.
If your solid state drive gets shorted out, you will see the SSD burnt and the SSD no longer working. You will see either a transistor component or a flash memory chip will have a physical burn mark on the component. We specialize in solid state drive repair so there is a good chance we can recover the data as long as the Flash Chip is not burnt out.
Another common failure is controller corruption or controller chip failure. The data that resides in the controller is the brains of the SSD. Since the SSD is constantly shuffling around your data there are times where it loses track of where it put your data. If that happens, the data still resides on the flash memory chips, but the drive no longer knows how the data is stored. Using our special machine we many times can correct the problem.
Types of SSDs
SLC: Back when a NAND chip were first created each cell had two states.
Not Charges = 0 Charged = 1
MLC: Then somebody had a bright idea.. Why don’t we measure the voltage in each cell and make
.5 Volts = 1 and 1 Volt = 2 and 1.5 Volt = 3 and 2 Volt = 4
TLC: Then someone said why only do 4 levels. Lets do 8 levels.
QLC: Then total insanity.. Lets do 16 Levels
They do this to reduce cost.
SLC: Sold to Industry and Government only.
MLC: Samsung 990 PRO 1TB $100
TLC: Samsung 870 EVO 1TB: $80
QLC: Samsung 870 QVO 1TB: $60
Life of a SSD[ Life of a SSD is rated in TBW (Terabytes Written)
Basically once you pass this value your SSD is at life.
Some examples of a 1TB
QVO 360 TBW
EVO 1200 TBW
PRO 2400 TBW
A good way to test your SSD is with a free program called CrystalDiskInfo.
They Call it: Total Host Writes
The SSD Above is at 176 TBW
Life for a 2TB EVO is 1,200 TBW so a little over 10% Life.
